摘　　要：为提高粗纺纱线条干均匀度,对50批38.5 tex粗纺纯绒纱的条干进行测试。采用ORIGIN 7.0软件和数理统计知识,对测试结果进行相关分析和回归模拟,建立纱线条干的经验方程。结果表明:细纱条干CV值和粗纱条干CV值之间线性关系显著;条干CV值与细节、毛粒之间也存在较强的线性相关性;条干CV值受细节的影响最大,其次是毛粒的影响,而粗节的影响基本可以忽略。研究结果为进一步改善粗纺纯绒纱线条干质量提供了理论参考。To improve the yam evenness, fifty batches of woollen cashmere yarns with the linear density ot 38.5 tex were involved. Softwares concerned such as ORIGIN 7.0 were adopted to carry out the correlation analysis. The model of yarn evenness is built. Relationship between single yarn evenness and roving evenness was investigated, and relationship between yarn evenness and parameters like thin place, thick place and neps was also investigated. It is possible to indicate that there is a positive correlation between single yarn evenness and roving evenness, meanwhile thin place is the most important factor as far as the evenness of woollen cashmere yarn is concerned. Minor influence of the amount of neps on the yarn evenness is noticed, while the influence of thick place can be neglected. The results provide theoretical basis for improving the yarn evenness.
